AbstractPeriviable infants (i.e., born before 26 complete weeks of gestation) represent fewer than .5% of births in the US but account for 40% of infant mortality and 20% of billed hospital obstetric costs. African American women contribute about 14% of live births in the US, but these include nearly a third of the country’s periviable births. Consistent with theory and with periviable births among other race/ethnicity groups, males predominate among African American periviable births in stressed populations. We test the hypothesis that the disparity in periviable male births among African American and non-Hispanic white populations responds to the African American unemployment rate because that indicator not only traces, but also contributes to, the prevalence of stress in the population. We use time-series methods that control for autocorrelation including secular trends, seasonality, and the tendency to remain elevated or depressed after high or low values. The racial disparity in male periviable birth increases by 4.45% for each percentage point increase in the unemployment rate of African Americans above its expected value. We infer that unemployment—a population stressor over which our institutions exercise considerable control—affects the disparity between African American and non-Hispanic white periviable births in the US.

Background: The importance of early institution of “Do Not Resuscitate” (DNR) orders in determining outcomes from intracerebral hemorrhage is established. In the setting of acute ischemic stroke, African Americans tend to utilize critical care interventions more and palliative care options less than Caucasians. Recent epidemiological studies in acute ischemic stroke have shown a somewhat better survival for African Americans compared with Caucasians. Our hypothesis was that racial differences in early institution of DNR orders would influence mortality in acute ischemic stroke. Methods: a retrospective chart review was conducted on consecutive admissions for acute ischemic stroke across 10 hospitals in Michigan for the year 2006. Subjects with self reported race as African American or Caucasian were selected. Demographics, stroke risk factors, pre morbid status, DNR by day 2 of admission, stroke outcome and discharge destination were abstracted. Results: The study included 574 subjects (144 African American, 25.1%; 430 Caucasian, 74.9%). In-hospital mortality was significantly higher among Caucasians (8.6% vs. 1.4% amongst African Americans, p=0.003). More Caucasians had institution of DNR by day 2 than African Americans (22.5% vs. 4.3%, p<0.0001). When adjusted for racial differences in DNR by day 2 status, Caucasian race no longer predicted mortality. Caucasians were significantly older than African Americans (median age 76 vs. 63.5 years, p<0.0001); and age was a significant predictor of DNR by day 2 and mortality. In the adjusted analysis, however, age marginally influenced the racial disparity in mortality ( table ). Caucasians with coronary disease, atrial fibrillation, severe strokes and unable to walk prior to the stroke tend to be made DNR by day 2 more frequently. Only 27.1% of Caucasians with early DNR orders died in the hospital, whereas 20.8% were eventually discharged home. Conclusions: Early DNR orders result in a racial disparity in mortality from acute ischemic stroke. A substantial proportion of patients with early DNR orders eventually go home. Postponing the use of DNR orders may allow aggressive critical care interventions that may potentially mitigate the racial differences in mortality.

There is no safe detectable level of lead (Pb) in the blood of young children. In the United States, predominantly African-American Black children are exposed to more Pb and present with the highest mean blood lead levels (BLLs). However, racial disparity has not been fully examined within risk factors for early childhood Pb exposure. Therefore, we conducted secondary analysis of blood Pb determinations for 2841 US children at ages 1–5 years with citizenship examined by the cross-sectional 1999 to 2010 National Health and Nutrition Examination Survey (NHANES). The primary measures were racial disparities for continuous BLLs or an elevated BLL (EBLL) ≥5 µg/dL in selected risk factors between non-Hispanic Black children (n = 608) and both non-Hispanic White (n = 1208) or Hispanic (n = 1025) children. Selected risk factors included indoor household smoking, low income or poverty, older housing built before 1978 or 1950, low primary guardian education <12th grade/general education diploma (GED), or younger age between 1 and 3 years. Data were analyzed using a regression model corrected for risk factors and other confounding variables. Overall, Black children had an adjusted +0.83 µg/dL blood Pb (95% CI 0.65 to 1.00, p < 0.001) and a 2.8 times higher odds of having an EBLL ≥5 µg/dL (95% CI 1.9 to 3.9, p < 0.001). When stratified by risk factor group, Black children had an adjusted 0.73 to 1.41 µg/dL more blood Pb (p < 0.001 respectively) and a 1.8 to 5.6 times higher odds of having an EBLL ≥5 µg/dL (p ≤ 0.05 respectively) for every selected risk factor that was tested. For Black children nationwide, one in four residing in pre-1950 housing and one in six living in poverty presented with an EBLL ≥5 µg/dL. In conclusion, significant nationwide racial disparity in blood Pb outcomes persist for predominantly African-American Black children even after correcting for risk factors and other variables. This racial disparity further persists within housing, socio-economic, and age-related risk factors of blood Pb outcomes that are much more severe for Black children.

5088 Background: To determine if racial disparity exists between African American (AA) and non-African American (NAA) patients with early stage uterine endometrioid carcinoma who had similar multidisciplinary management. Methods: Our prospectively-maintained database of 1,450 uterine cancer patients was reviewed for this IRB-approved study. We identified 766 consecutive patients with endometrioid carcinoma 1988 FIGO stages I-II who underwent hysterectomy between 1987-2009. Patients with non-endometrioid carcinoma, mixed histologies and those who received preoperative treatments were excluded. For the purpose of data analysis, patients were divided into two groups; AA and NAA. Recurrence-free survival (RFS), disease specific (DSS) and overall survival (OS) was calculated from the date of hysterectomy using the Kaplan-Meier method. Cox regression modeling was used to explore the risks of various factors on recurrence. Results: Median follow-up was 5.1 years. 27% were AA and 73% were NAA. All patients underwent hysterectomy and oophorectomy. 80% had peritoneal cytology and 69% underwent lymphadenectomy. AA patients were more likely to have higher grade tumors, and more lymphovascular space involvement (LVSI). Although the two groups were balanced in regards to surgical staging and adjuvant treatment received, the five-year RFS and DSS were significantly lower in AA compared to NAA patients (91% vs 84%, p=0.030; 95% vs 88%, p=0.011, respectively). Between the two groups, OS was not significantly different. On multivariate analysis and after adjusting for other prognostic factors, race (AA vs NAA) was not a significant predictor of outcome. Grade 3 tumors and the presence of LVSI were the only two independent predictors of RFS and DSS with p=<0.001 and p=<0.001, respectively. Conclusions: In this large hospital-based study, AA race was associated with a higher incidence of adverse pathological features and worse recurrence-free and disease-specific survival. However, on multivariate analysis race was not an independent prognostic factor. Further studies are needed to elucidate possible underlying molecular mechanisms for these poorer outcomes.
